(These man pages exist in Debian or Ubuntu. YMMV with other distros.)

Each of these is a plain ascii file that shows the translation between
numbers (protocol, port, or network IP address) and human-readable
names. Some Linux distros may use /etc/sysconfig/networks instead of
/etc/networks. The /etc(/sysconfig)/networks file, like /etc/hosts, is
maintained by the local sysadmin. Unlike /etc/hosts, I don't think
/etc/networks is required for network operation.

The other two files are part of the basic OS distribution (the netbase
package in Debian or Debian-based distros). On my system, the
/etc/protocols ane /etc/services files begin with comments which contain
URLs to www.iana.org.

Correct, but you can use it to alias your networks, making
administration easier.

Here is an example of ane /etc/networks file where the local network is
192.168.1. and all the hosts are on that subnet. (This the linksys
router default)

loopback 127.0.0.0
homenet 192.168.1.0
